COMPARISON OF VISUAL OUTCOMES AFTER CATARACT SURGERY IN DIABETIC VS NON-DIABETIC PATIENTS IN SHEIKH ZAYED HOSPITAL, RAHIM YAR KHAN

Abstract

This comparative observational study evaluated visual outcomes following cataract surgery in diabetic and non diabetic patients at Sheikh Zayed Hospital, Rahim Yar Khan. A total of 100 patients were enrolled, equally divided into diabetic and non diabetic groups, and assessed preoperatively and postoperatively at Day 1, Week 1, and Week 6. Visual acuity, complications, retinal status, and patient satisfaction were analyzed. Both groups demonstrated significant improvement in best corrected visual acuity, with 71% reporting improved or much improved vision. Early postoperative complications such as mild corneal edema were common but resolved by six weeks, while posterior capsular opacification occurred in 35% of cases. Statistical analysis revealed no significant difference in visual improvement between diabetic and non diabetic patients (χ² = 4.848, p = 0.303). Overall, cataract surgery was safe and effective in both groups, with high patient satisfaction, provided adequate preoperative evaluation and glycemic control were ensured.
